Question

Having trouble finding anything on this or if anyone can direct me to a question already asked, that would be great.

Table Customer

ORDER,      QTY_ORDER  
A1234 ,        5

Select Output

ORDER,          QTY_ORDER  
A1234,            1 OF 5  
A1234,            2 OF 5  
A1234,            3 OF 5  
A1234,            4 OF 5  
A1234,            5 OF 5

Answer 1

First: using ORDER as a column name is a terrible idea.

(I used order_id as the column name instead, to make things easier)

with order_rows as (
   select distinct c.order_id, level as lvl, c.qty_order
   from customer c
   connect by level <= c.qty_order
)
select r.order_id, to_char(r.lvl)||' of '||r.qty_order
from order_rows r
order by order_id, lvl;

But that is not going to be very efficient.
